15 Minute Sand Timer

A fifteen-minute sand timer marks a proper work block. For students who struggle to gauge time, a quarter-hour of visible sand turns “work until the timer's done” into a target they can actually see approaching.

Why a 15-minute sand timer helps focus

About the 15 Minute Sand Timer

Fifteen minutes of sand is substantial but not overwhelming — long enough for real focus, with a steady flow that gives an anxious or restless learner something calming to check instead of the clock.

Frequently Asked Questions

Does the 15 minute sand timer keep accurate time in the background?

Yes. It counts down against the real clock rather than ticking in the tab, so your 15 minute sand timer stays accurate even if you switch tabs or lock your screen — and the alarm still sounds at zero.

Can I change the duration, or switch away from the sand clockface?

This page opens preset to 15 minutes on the Sand clockface, but you can set any duration and switch to a different clockface at any time using the controls below the timer.
